Sliding-Housing Display for Content Aspect-Ratio Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays with fixed aspect ratios inefficiently utilize display area when displaying content with different aspect ratios, often resulting in letterboxing or partial content cutoff.
Innovation Solution
An electronic device with a variable display area, comprising a first and second housing that slide relative to each other, controlled by a processor to adjust the display area based on the aspect ratio of the content, minimizing letterboxing through automatic or user-induced sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional display with fixed aspect ratio is used, then the display structure is simple and easy to manufacture, but the display area utilization is inefficient when displaying content with different aspect ratios
Solution Approach 1:
The display structure transitions from a fixed state to a dynamic, adjustable state. The second housing is made slidable relative to the first housing, allowing the display area to dynamically adjust its size and aspect ratio based on the content being displayed, thereby resolving the contradiction between fixed structure simplicity and adaptive display efficiency
Solution Approach 2:
The display system is divided into separable components: a first housing containing the display, and a second housing that can slide relative to it. This segmentation allows independent optimization of each component while enabling flexible reconfiguration of the overall display area to match different content aspect ratios
2Area of stationary object
If the display area is fixed, then the device structure is simple, but letterboxing occurs and display area is wasted when content aspect ratio does not match
Solution Approach 1:
The physical parameters of the display area (size and aspect ratio) are made changeable through the sliding mechanism. By adjusting the position of the second housing, the display area parameters can be changed to precisely match the content aspect ratio, eliminating letterboxing and maximizing display area utilization without wasting display real estate
3Productivity
If the display area is adjusted to match content aspect ratio, then display area utilization is optimized, but the device requires additional sliding mechanism increasing complexity
Solution Approach 1:
The sliding mechanism serves multiple functions: it adjusts the display area size, changes the aspect ratio, and can be controlled automatically based on content detection. This multi-functionality justifies the added complexity by providing comprehensive display optimization across various content types without requiring separate mechanisms for each function

AI summary
An electronic device is provided. The electronic device includes a first housing, a second housing slidable with respect to the first housing, a display having one end fixed to the second housing and having a variable information display area in which information is visually displayed according to sliding of the second housing, a sliding motor, and a processor operatively connected to the display and the sliding motor and, when an application is executed, the processor acquires first information including a display ratio of application-related information that is be displayed on the display by executing the application, acquires second information including a screen ratio according to the information display area of the display, compares the first information with the second information, and controls the sliding motor on the basis of the comparison result.
